Dermatitis Herpetiformis

What is dermatitis herpetiformis?

Dermatitis herpetiformis is an intensely pruritic (itchy) skin disease characterized by eruptions of clusters of small blisters or vesicles (small elevations of the skin containing fluid) and small bumps or papules (small, solid, elevations on the skin). Dermatitis herpetiformis usually occurs in young adults. It affects more men than women.

What triggers dermatitis herpetiformis?

Dermatitis herpetiformis is related to the presence of IgA deposits under the skin. These deposits occur in response to consuming glutens (proteins) in the diet, such as those found in wheat, barley, rye, and oat products. However, once IgA deposits occur, they are slowly cleared by the body even when the individual is gluten free. The disease is not common among African-Americans or Asians. Persons with dermatitis herpetiformis often have a high incidence of autoimmune disorders and thyroid disease.

Treatment for dermatitis herpetiformis:

Specific treatment for dermatitis herpetiformis will be determined by your physician based on:

* your age, overall health, and medical history

* extent of the condition

* your tolerance for specific medications, procedures, and therapies

* expectation for the course of the condition

* your opinion or preference

The symptoms of dermatitis herpetiformis may clear when all gluten is eliminated from the diet, although healing may take several weeks to months. Treatment may also include drug therapy. Dapsone, a medication which can improve symptoms by suppressing the skin response, may be prescribed. However, dapsone has been associated with some side effects, especially anemia. Your physician will carefully monitor your blood count, if prescribed this medication.
